DOOR-LATCH.

Specification of Letters Patent.

Patented July 18, 12%16.

Application filed April 8, 1916. Serial No. 89,930.

To all whom it may concern:

Be it known that I, JOHN HERMAN JoNEsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door-Latches,

of which the following is a specification,

reference being had to the accompanying drawings.

This invention relates to improvements in sliding or swinging closure latches or fastening devices and has particular reference to a latch which is especially adapted for use upon sliding doors although it will be found equally as efficient when used upon various other types of closures.

The principal object of the invention resides in the provision of a latch which will serve not only to retain the door in a closed position by reason of its being susceptible of securementby means of a padlock or the like, but which will also serve the important purpose of retaining the door in snug engagement with the frame when in a closed position to prevent rattling of the door and exclude the entrance of snow, rain, wind or the like between the door and the frame.

Another object is to provide a latch of this character which is simple in construction and which may be quickly applied to the usual types of doors now in common use and which may be operated from either the inner or the outer side of a door mounted for swinging movement.

It is well known that projections upon the inner faces of sliding doors are not permissible unless a specially constructed door frame is provided and therefore it is another object of the invention to provide a latch which will automatically operate upon its release from an operative position to arrange itself entirely within the plane of the inner face of the door.

lVith the foregoing and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In the drawings, Figure 1 is a fragmentary front elevation of a sliding door structure equipped with the improved latch; Fig.

is a horizontal sectional view therethrough; Fig. 3 is a fragmentary inner face view of a portion of the door.

Referring to the drawings by numerals wherein is illustrated the preferred embodiment of my invention, '1 designates a portion of a building structure such as a barn, car or the like which is provided with the usual door opening 2 surrounded by the door frame 3. The frame 3 is as usual arranged upon the inner face of the building structure and arranged upon the outer face of the building structure and surrounding the door opening is a frame 4 which serves to hold the door 5 in spaced relation to the side of the structure 1 when the same is in a closed position.

' Opposite sides of the frame 4, that is portions thereof, one adjacent either side of the away as indicated at 10 door frame, are cut and the outer open sides of these cut-away portions are closed by plates 11 secured to the frame in any suitable manner so that keepers are provided for a purpose which will presently appear.

lVhen the door is in a closed position, its inner face is adapted to abut the outer face of the frame 4, but when the same is in an open position its inner face will be arranged in spaced relation to the outer face of the.

building structure so that no frictional en gagement of the door with any portion of the building will effect its eflicient sliding operation. One side of the frame 41 is provided with a strip or stop 12 against which one vertical edge of the door is adapted to abut to limit itsinward sliding-or closing position and this strip is provided upon its outer face with a staple 13 for a purpose which will likewise presently appear.

A transverse opening is provided in the door 2 near its edge and in horizontal alinement with the staple 13 and this opening has extending therethrough a bolt 14 which is threaded upon its inner end, that is the end projecting beyond the inner face of the door, to threadedly receive a catch 15, said catch being'secured against rotation upon the bolt after being threaded thereon in any suitable manner. The outer face of the door has secured thereto a plate 16 which extends over the opening and has the bolt 14 passing therethrough, the bolt extending any suitable distance beyond the outer face of the plate and terminating in a handle 17. A

washer 18 is arranged upon the bolt and abuts the handle and between this washer and the plate 16 is arranged a coiled expansion spring 19 which serves to normally hold the catch 15 in engagement with the inner face of the door. A recess 20 is formed in the inner face of the door so that by rotating the handle 17 until alined with the recess, the spring 19 will operate to draw the bolt outwardly and move the catch into engagement with the recess whereby no portion of the same will project beyond the plane of the inner face of the door. This permits of the free opening or closing of the door as will be understood. When the door is moved to a closed position and it is desired to latch the same, the handle 17 is pressed inwardly to disengage the catch from the recess and is then rotated to swing the catch within the cutaway portion 10 of the frame 4 between the plate 11 and the frame 3, or, in other words, within the keeper. Then by releasing the handle, the spring 19 exerts a tension against the outer face of the door to force the same inwardly in snug engagement with the frame. When in this position a padlock 21 may have its hasp passed through the staple 13 and handle 17 and then looked to thus lock the door in a closed position. A second latch indicated in its entirety at 22 is provided in the opposite side of the door and is adapted to be operated to engage the keeper in the door frame opposite to the first-mentioned keeper when the door is in a closed position to bring all the parts of the door into snug engagement with the frame. In this connection it is to be noted that the latch to one side of the door prevents movement of the same in one direction while that to the other side prevents movement of the door in the opposite direction, so that for all ordinary purposes the two latch members serve to lock the door in a closed position as well Copies of this patent may be obtained for the catch is frame havthrough and rotatably supported by said door, a laterally disposed elongated catch secured to one end of the bolt and overlying a face of the door and adapted for engagement with the keeper, said bolt being capable of endwise movement, the operating portion of the bolt being arranged beyond the opposite face of the door, a recess in the first named face of the door adapted to receive the catch when released from the keeper, said recess being adapted to snugly receive the catch and being of such a depth as to substantially entirely receive the catch,

said recess serving, when the catch is positioncd therein, to hold the bolt against ro tatable movement, and an expansible spring interposed between the door and the operating portion of the bolt.

In testimony whereof I hereunto aiiiX my signature in the presence of two witnesses. J. HERMAN JONESON.
